Title: Method for sticking a belt-like member and apparatus therefor
Inventor: OKUYAMA KOJI
IPC: B29D30/30
Filed: 1989-12-13
Abstract: Abstract A  method  and  an  apparatus  for  sticking  a  belt-like member, wherein a belt-like member prepared by cutting a raw material of the belt-like member on a conveyor at two front and  rear  locations,  is  conveyed  by  the  conveyor,  wrapped around  a  cylindrical  drum  and  stuck  to  the  drum.    The inclination angle of the cut line at the leading end of the belt-like member  is measured at  the  time of  cutting,  the inclination angle of  the cut  line at  the trailing  end  is measured  at  the  time  of  cutting,  and  by  comparing  the inclination of  the cut  line at  the  trailing  end with the inclination angle at the leading end, an amount of correction for the inclination angle is calculated.   After cutting at the trailing end, the trailing end portion is attracted and held by an attracting device, and by rotating this attracting device  on  the  basis  of  the  aforementioned  amount  of correction for the inclination angle,  the inclination angle of the cut line at the trailing end is corrected so as to coincide with the inclination angle of the cut line at the leading end.  While maintaining this corrected condition, the belt-like member is wrapped around the cylindrical drum and stuck to the drum.  The belt-like member after completion of wrapping has its leading end edge and its trailing end edge surly coincide with each other, and a step-shaped deviation or the like would not arise.

Abstract: ABSTRACT       A recovery apparatus for a training torpedo built to replicate an operational torpedo.  The training torpedo is an elongated hollow housing substantially similar in shape to an operational torpedo.  The nose portion is a shell having a forward and aft portion, the forward portion being a cylindrical cavity extending longitudinally into the shell. A cylindrically shaped piston is adapted to be inserted into cylindrical cavity of the shell.  The piston has a forward and a rear portion, the forward portion being a pressure receiving surface.  The piston is able to move forward and aft with respect to the shell.  Attached to the piston is a retaining means.  When a pressure is imposed upon the forward portion of the piston the piston moves aft and the retaining means releases a plurality of weights.          Located between the piston and the shell is a damping means.  The damping means acts as a counter force to the pressure on the pressure receiving surface of the piston.

Title: Thermoplastic matrix filament winding head
Inventor: GUNYUZLU MARK A
IPC: B29C53/56
Filed: 1990-09-24
Abstract: ABSTRACT          Thermoplastic matrix composite cylinders, pipes, and other hollow bodies are formed by a winding technique using thermoplastic filaments.  The filaments are fed from a vertically moving winding head onto the surface of a rotating mandrel.  The filaments are preheated to soften them and then pass beneath a heated compaction roller bearing against the mandrel.  The compaction roller is castered so as to follow a spiral path.  Several plies of the thermoplastic material may be laid down in this fashion, the surface of each prior ply being heated so that the layers fuse properly.  When cooled to below its solidification temperature, the formed object is removed from the mandrel.

Title: Dual-lumen catheter apparatus and method
Inventor: WORTLEY RONALD W
IPC: A61M25/00
Filed: 1990-11-07
Abstract: A  dual  lumen  catheter  apparatus  and  method.    The apparatus has an elongated catheter body adapted for insertion into a vein or a fluid-containing body cavity of a patient such as the right atrium of a heart.  The catheter body has a septum that runs longitudinally through the interior of the catheter body so as to divide the interior of the catheter into a first and a second lumen.  The septum is offset from the longitudinal center axis of the catheter so that the cross-sectional area of the two lumens are of different sizes.    The first lumen has a cross-sectional size that is relatively large so that a sufficient volumetric flow rate of blood that is to be oxygenated is able to flow by means of gravity drainage through the first lumen whereas the second lumen is smaller but is still sufficiently large so that an essentially equal volumetric flow rate of blood that has been oxygenated can be returned under pressure through the second lumen.

Title: Leak monitor for hydraulic drive systems
Inventor: KUNZE HANS-JUERGEN
IPC: G01M3/26
Filed: 1990-05-18
Abstract: ABSTRACT         Leak Monitor for Hydraulic Drive Systems The drive systems include at least one conduit leading to a machine unit which may be selectively connected to a pump or a tank.  Arranged in the conduit is a holding valve which, when the conduit is connected to the tank, maintains a minimum pressure in the conduit branch leading  to the machine  unit.    A pressure sensor arranged in this conduit branch determines the actual value of the conduit pressure.  If this decreases with respect to the minimum pressure predetermined by the opening  pressure  of  the holding  valve,  which  is determined  by  a  comparison  device,   this  is  an indication that the conduit section has a leak, if only a small one.

Title: Apparatus for producing textured nonwoven fabric and related method of manufacture
Inventor: GREENWAY JOHN M
IPC: D04H1/46
Filed: 1991-01-03
Abstract: An apparatus and related process for entangling a fibrous web which employs columnar fluid jets to eject a continuous curtain of fluid in an entangling station. The web is advanced through an entangling station on a conveyor which supports an entangling member having a symmetrical pattern of void areas. Baffle members disposed in the void areas are provided which include radiused curvatures and define apertures having a frusto-conical configuration.      Dynamic forces in the fluid curtain impact the web in discrete and controlled patterns determined by the baffling members to enhance efficient energy transfer and web entanglement. Textile-like fabrics having a uniform, non-apertured, surface cover are obtained by coaction of fluid curtain and baffle structures.

Title: Arrangement for automated troubleshooting using selective advice and a learning knowledge base

IPC: G06F11/25
Filed: 1991-02-25
Abstract: AN ARRANGEMENT FOR AUTOMATED TROUBLESHOOTING USING      SELECTIVE ADVICE AND A LEARNING KNOWLEDGE BASE Abstract Troubleshooting expert systems are generally embodied in software for the purpose of solving difficult problems in some narrow domain of expertise. The prior art describes certain mechanics for developing or generating rules. That process is commonly known as the knowledge acquisition process. Having acquired the knowledge, our new troubleshooting arrangement eliminates the prior art separation between the expert system knowledge acquisition process and the expert system utilization process. Our new arrangement also detects and classifies invalid actions or other errors of the user in a manner that allows for the non-human expert system to advise the human user. Our arrangement interactively communicates between a user and a troubleshooting system, generates a learning knowledge base, identifies an object being tested by the user, utilizes the learning knowledge base for troubleshooting the test object, and classifies the test object as faulty or not faulty. Our arrangement structures prior actions of the user as pairs of elements in a multi-branch tree in the learning knowledge base and the compares present actions of the user with the prior actions of the user. A current signal path is generated between a first input and a first output in the system under test. Then, it can be determined whether the test object belongs to the current signal path. Responsive to the comparison of the actions of the user andresponsive to whether the test object belongs to the current path, the skill level of the user can be classified into one of a plurality of skill levels. Responsive to the skill level classification of the user, the kind of troubleshooting advice to be given the user can be classified as to one of a plurality of kinds of troubleshooting advice and thereafter the advice can be communicated to the user. Further, the output of the test object can be measured and a new current signal path can be generated and re-generated for identifying a faulty object in the system under test.
